Description
Technical field
The utility model is related to a kind of water-ring vacuum pumps with high axial positioning function.
Background technology
Power industry has operational reliability and service life very harsh requirement to vacuum pump used, and traditional
Applied to the double rib bearings of bearing generally use one in the vacuum pump structure of power industry, supporting impeller axle both ends or one
Axially position of the ball bearing as vane rotor, axial motion is easily generated using process, is caused impeller operation vibrations big, is reduced
Stability under high vacuum state.
Invention content
The technical problems to be solved in the utility model is：In order to overcome deficiency in the prior art, the utility model provides
A kind of water-ring vacuum pump with high axial positioning function that can effectively prevent vibration, improve operation stability.
Technical solution is used by the utility model solves its technical problem：A kind of water with high axial positioning function
Ring vacuum pumps, including pump case, the end cap for being installed on pump case both ends, impeller axle and the impeller in impeller axle, outside end cap
Bearing block is fixed on side, a pair of bearings of support impeller axle is equipped in bearing block, the bearing is tapered roller bearing,
Two bearing tapers backwards to and spacing be mounted in impeller axle, relative to having on the bearing block of interstitial site between two bearings
Lubrication hole is packed with being impregnated with the sliver of lubricating oil in lubrication hole.
The lubrication hole upper port is equipped with the plug screw being tightened against on bearing block.
The beneficial effects of the utility model are：The utility model uses bearings leaf of two rolling elements for conical roller
Wheel shaft, and the taper of two bearings realizes the axially position to impeller, can be effectively prevented vacuum pump operation process backwards to setting
The axial motion phenomenon of middle generation, and can pre-adjusted axial gap；It is acted on, carried by being impregnated with the sliver of lubricating oil simultaneously
Height extends bearing service life, it is ensured that the stabilization of performance when vacuum pump operates under high vacuum state to the lubricant effect of bearing
Property.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
A kind of water-ring vacuum pump with high axial positioning function as shown in Figure 1, including pump case 1, is installed on pump case 1
End cap 2, impeller axle 3 and the impeller 4 in impeller axle 3 at both ends are fixed with bearing block 5, bearing block on 2 lateral surface of end cap
5 outer end faces are fixed with gland.
A pair of bearings 6 of support impeller axle 3 is equipped in the bearing block 5, the bearing 6 is conical roller axis
It holds, two 6 tapers of bearing are mounted on backwards to simultaneously spacing in impeller axle 3, relative to the bearing block of interstitial site between two bearings 6
On 5 there is lubrication hole 7, be packed with being impregnated with the sliver 8 of lubricating oil in lubrication hole 7, while be equipped with and twist in 7 upper port of lubrication hole
Tightly in the plug screw 9 on bearing block 5.It is placed in lubrication hole 7 soaked with the sliver of lubricating oil 8 during use, plug screw 9 is screwed on, in vacuum
It pumping in operation process, the lubricating oil contained in sliver 8 can slowly flow into two bearings 5, reach the lubricating action to bearing 5,
With after a period of time, the sliver 8 that lubricating oil has been lost in from lubrication hole 7 is extracted out, changes the new sliver for being impregnated with lubricating oil
8。
The utility model uses two rolling elements to support impeller axle 3, and the cone of two bearings 6 for the bearing 6 of conical roller
Degree realizes the axially position to impeller 4, can be effectively prevented the axial motion occurred in vacuum pump operation process and show backwards to setting
As, and can pre-adjusted axial gap；It is acted on simultaneously by being impregnated with the sliver 8 of lubricating oil, improves the lubrication effect to bearing 6
Fruit extends 6 service life of bearing, it is ensured that the stability of performance when vacuum pump operates under high vacuum state.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to novel technical scope on specification, it is necessary to which its technology is determined according to right
Property range.
